No, it's not. :)
I built two access ramps this afternoon from scrap dimensional, AC2 and CDX ply.
Free is good. :)
When I was a kid we built a fort using scrap wood from projects. Piled them on a red flyer wagon and hauled them back home. (Had to straighten out the axles more than once.)
Used pallets as the foundation. We knew better, but convinced ourselves that the crappy looking 4’x8’ plywood left out was also “scrap”. (As I got older I figured those were probably for foundation forms.)
